Embodiment Construction

[0052] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, to one skilled in the art that the present disclosure may be practiced without these specific details. In other instances, structures and devices are shown in block diagram form only in order to avoid obscuring the disclosure.

[0053] Reference to "one embodiment" or "an embodiment" in this specification means that a specific feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are different or alternative embodiments mutually exclusive of other embodiments. Furthermore, various features are described which may be exhibited by so...

Abstract

A communication network (100; 200) and method for transfer of information are disclosed. The communication network (100; 200) includes plurality of industrial systems (110, 160; 210, 220, 250, 280). Each system includes I / O board (120, 170; 212, 225, 255, 285) including I / O modules (130, 180; 235, 265, 295), at least one of an optical emitter (125; 215, 240, 270, 298) and an optical receiver (175; 230, 260, 290), and a processing module (140, 190; 245). The processing module (140, 190; 245) and the I / O board (120, 170; 212, 225, 255, 285) generate an optical signal corresponding to information and a Cyclic Redundancy Check (CRC) information. The network (100; 200) includes a first optical bus (150) and a second optical bus (155) coupled with the I / O boards (120, 170; 212, 225, 255, 285) for transferring the optical signal and complement of the optical signal between the systems.

Description

technical field [0001] The present disclosure relates to methods and systems for reliable information transfer between industrial systems using optical networks. Background technique [0002] Industrial equipment may have various systems such as control stations, machinery, and other components interconnected in a network. Networks are used to transfer a variety of information between systems, such as process-related information, telemetry information, and other monitoring and control information. Systems of such industrial equipment can be placed at distances of up to several kilometers (km) from each other. [0003] In an exemplary case, a communication channel, such as an Ethernet-based channel, is used to transfer information between the various systems of industrial equipment over physical wires, such as copper or any other metal wire. However, such channels have a certain degree of delay and are indeterminate as the traffic of information increases between systems. ...
